Cosmo's Diner

Amazing breakfast place with a HUGE menu. The coffee and food were excellent and the service super friendly. Has an 50s theme inside with the decor, retro chairs and tables. The prices are fair and the service was fast. If you are in the area, be sure to drop by, you won't be disappointed!

My friend and I come to Cosmo's all the time and we love it! We usually get the 'YOU ARE FABULOUS' (two eggs, bacon, home fries and toast). Eggs and bacon are always made exactly to order (soft poached, crispy bacon, thank you very much.) The service is impeccable! Friendly, efficient, and attentive - even when a surprise walk-in group of 30 hockey players pops by, my food arrives quickly, hot, and delicious. I love that the coffee comes with a carafe and my cup is always full. The music and décor is fifties and fun. Amenities are clean. Prices are very reasonable. Highly recommend.

This place is incredible! The menu is extensive and the food was delicious. Highly recommend the lobster grilled cheese, and the lemon ricotta pancakes with blueberry sauce. 🤤 The ambiance was nice - really enjoyed their music selection playing at the right volume in the background. The waitress was super friendly and attentive. The only complaint would be the cleanliness of the bathroom and sticky floor. Other than that, 100% recommend and will be going back for more!

Located on Front Street with plenty of street and a large parking lot at the back of the restaurant. There is a large menu to select from and indulged with the steak & eggs paired with rye toast and sweet potato fries. The steak was cooked perfectly paired with the sunny side eggs and well toasted bread to sop up the yolks with. The coffee was endless and even provided a carafe to satisfy my coffee addiction. The staff here are super friendly and love the decor and vibe. Definitely a must goto if you are in the Niagara region and want to enjoy a nice breakfast.

Love this place. Great menu selection. Great customer service and funky retro diner atmosphere. Prices are very reasonable. Check them out!!
